HINGE AND AUTOMATIC CATCH FOR -AWNING-BLINDS.'

SPECIFICATION forming part of Letters Patent No. 752,348, dated February 16, 1904.

Application filed July 10, 1902. Serial No. 115,045. (No model.)

To all whom it may concern:

Be it known that I, FRANK W. Lur'rs, a citizen of the United States of America, and a- IO My invention relates to window-blinds for dwellings; and it consists in the means shown and described whereby a shutter may be hinged at the top to be swungout-from the bottom to subserve the purpose of an awning and where- 5 by it may be hinged to be swung open in the ordinary way and in the means shown and described whereby the blind may be automatically locked in a predetermined position when swung outward and means for securing the 20 pintle of the lower hinge in place.

The devices may be applied to any ordinary window-blind for the purpose specified.

A specific description of the remaining features of my invention will be obtained through 5 reference to the annexed drawings, wherein' Figure 1 shows a pair of window-blinds in their displayed position to serve as an awning and embodying my invention. Fig. 2 is an enlarged detail of the automatic locking and 3 supporting mechanism attached to the right half of the blind or shutter with the latter closed against the casement. Fig. 3 represents an edge elevation of the same with the casing and its lower hinge in dotted lines.

35 Fig. 4 indicates a plan of one of the stiles with the upper blind hinge or support thereto secured. Fig. 5 is an elevation of the same in the position indicated in Fig. 2 and the blind shown in dotted lines thrown partially 1 outward. Fig. 6 is a horizontal section on line 8 8 of Fig. 2, showing the finger-spring in the locked and the released position in dotted lines. Fig. 7 designatesa modification of the blind-support and adjustable staple with $5 the blind in an extended position.

Corresponding numerals designate similar features throughout the several figures of the drawings, referring to which 1 1 denote right and left members and when i united forming the window-blind, each be- 1 to 7, these sockets in either position rest upon the upper edges of the staples 2 2, which with the casement-head 8 form a rest or hearing, so

that the blind cannot become unhinged or sag.

The lower staples 9 9 are provided with bearings 10 and sockets 11, the former seating the thrust and the latter receiving the sustainingrods 12 12, the lower ends of which, 13 13, are

sinuous in form, so as to retain their position against dislodgment when the blind is extended or closed in practical use, yet easily withdrawn by partially closing the blind, as indicated in dotted lines, Fig. 1, andlifting it from the staples 2 2, which permits the ends 13 13 to be withdrawn from their sockets 11 11. The upper ends of said rods 12 12 terminate in slotted plates 14 14, placed at right angles with the said rods and which receive the supporting-bars 15 15, also terminating at their lower ends with similar positioned and slotted plates 16 16, which in turn receive the rods 12 12. 7 Thus loosely united they slide approximately parallel with and over each other in opening and. closing the blind; To engage said members 12 and 15 at definite angles to support the blind, indents 17 17 are formed transversely andin the upper edge of said bars 15 15, which receive the plates 14 14 and securely hold them at the desired angle, the bars being connected to the stiles 7 by pivotal bearings 18 18.

To lock the closed blind against the case- Inent, I provide the plates 19 19, Fig. 1, comprising in detail, Fig. 2, the catches 2O 20 and the attached confining and releasing spring 2121, (delineated in Figs. 2, 3, and 6,) which operate as follows: The blind being brought in juxtaposition to the easement, the coacting rods 12 12 and bars 15 15, forming the extensions, assume the vertical position illustrated, I

the sinuous ends 13 13 of the rods lying in the path inclosed by the catches 20 20 and the noses 22 22 of the springs 21 21. The diameter of the rods 12 12 exceeding the space between said catches and springs obviously forces the passage, thrusting the spring parts 22 to the position shown in dotted lines 22, Fig. 6. The blind being closed, the noses 22 22 regain their original positions in line with said rod ends 13 13, and thus effectually secure the blind. In conjunction with the parts 22 the lips 23, formed by reflexing a portion of the plates 19, act as a stop to the rods 12 and also hold them against the noses 22. Similarly-formed lips 24: 24, coacting with the lower edges of the catches 2O 20 and the staples 9 9, prevent unshipping the blind in its closed position. To release the catches 2O 20, a slight pressure upward on the finger-pieces 25 25 retracts the springs 21 21 aside from the rods 12 12, as observed in dotted lines, Fig. 6, permitting the blinds to be swung outward. The springs, together with the plates, are secured by the screws 26 to the outer stile 7 of each blind-section, substantially as illustrated.

Obviously there may be other modifications structurally departing from the manner herein described Therefore I desire not to be held to the strict interpretation herein disclosed, but may use such equivalents, therefore, as would come within the fair scope and spirit of my invention, which having described I desire to secure by Letters Patent of the United States and claim 1. A pintle-receiving plate having double sockets and adapted to be attached to the upper and outer portion of the window-stiles, a staple provided with a curved pintle coacting with said sockets and adapted to be secured near the tops of the window-casings contiguous to said stiles, and additionally adapted to form a bearing for the empty sockets, when the bottoms of said blinds are moved horizontally outward or inward, to prevent by the contact of said sockets with the casement-head the displacement of the shutter as specified, said devices constructed to be interchangeable and adapted to suspend the blinds in a perpendicular and a horizontal position, as specified.

2. In combination with a window-blind, a staple having a bearing and a socket superimposed above said bearing, a sustaining-rod having a sinuous lower end adapted to be temporarily retained in said socketand resting upon said bearing, and provided with a slot-' ted plate at its upper end, means slidingly embraced by said plate and pivoted to the stile to automatically support in an adjustable manner the blinds in predetermined positions horizontally to form an awning as hereinbefore specified.

3. In a window-blind adapted as an awning, the locking-plate provided'with the catch 20, adapted to automatically receive and secure the adjustable extensions 12 and 15 in their closed positions, and having lips 23 and 24, the former as a stop to the rod 12 and the latter to prevent unshipment of the closed blinds, the attached spring 21 having a nose arranged to lie in the path of, and contiguous to said rod, and the finger-piece 25 actuating the spring to release the assembled extensions when the-blind is to be extended substantially in the manner described.

1. In a blind convertible from a single to a double awning-shutter, a locking-plate having a catch automatically securing the closed extensionsfa supporting-bar coacting with said locking-plate when the shutter is closed, and a sustaining-rod adjustably united to the supporting-bar in a manner to regulate the distance of the shutter from the casement; in combination therewith a staple forming the lower hinge provided with a bearing upholding said sustaining-rod, and a superimposed socket movably supporting the rod either in extended or closed position of the shutter as specified.
